What is the purpose of a portable conduit fishing system?

  1. To repair damaged conduits

  2. To blow a pull-line through the conduit

  3. To cut conduits to length

  4. To test conduit integrity

The correct answer is: To blow a pull-line through the conduit

The purpose of a portable conduit fishing system is to effectively blow a pull-line through a conduit. This system utilizes air pressure or a similar mechanism to push or pull a lightweight line through the length of the conduit, which is essential for the installation of wires or cables. Once the pull-line is successfully installed, it serves as a guide for pulling larger cables through the conduit, facilitating efficient electrical installations in both residential and commercial projects. This method is particularly useful when dealing with long or complex conduit runs where manual methods might be impractical or inefficient. In many scenarios, it eliminates the need for more invasive approaches, making it a valuable tool in a construction coordinator's toolkit. The other options focus on different tasks that don't align with the primary function of a portable conduit fishing system. For instance, repairing damaged conduits, cutting conduits to size, or testing their integrity involve different tools and techniques unrelated to the specific function of pulling lines through conduits.
